There’s Memphis again. We’re not even to the M’s yet. I remember reading a “Peanuts” comic as a kid in which Linus said he got the only A on his geography test because no one else in his class knew where Ipanema was. Took me years to get that joke. “Goodnight Houston” is a riff on “Goodnight Moon” and is thus completely unlike “Goodnight Saigon”.
